bitbake: codeparser: Improve handling of data.expand() dependencies

Currently bitbake doesn't parse into data.expand() expressions,
relying on high level expansion of python code to handle this.

One of the tests does however test this works.

We don't really want to be doing string expansion on python code,
so specifically parse into expand() function calls so that when
the high level behaviour is tweaked, the self tests continue to
pass and that we do continue to handle expand() function calls as
best we can.
